Mercury Insurance Customer Service

We found two options for the Mercury Insurance phone number customers can call. The first is a sales number and the second a billing number. Sales is for customers who don’-t have a policy and billing would have to be reserved for customers who need questions answered about their current policy.

Sales: 1-800-956-3728

Billing: 1-800-503-3724

Mercury Insurance Mailing Address

We found the address for the main headquarters after a little searching. The address is not listed on the Mercury Insurance website, but we were able to locate it. We emailed the customer service department to see if there is another mailing address for customer service issues.
